TRACTIQN-ENJGINE.

To all whom it may concern: 1 Be it known that 1,.BERT '0. BALL, acitizen of the United States, residing at Port land, in' the county ofMultnomah and State of Oregon, have invented new and usefulImprovements: in Traction-Engines, of which the following aspecification.

This invention relates to. traction engines and consists in certainimprovements in the construction thereof as will be hereinafter fullydescribed and pointed out inthe claims. The invention is illustrated inthe accompanying drawings as follows:.-

Figure, 1 shows a plan view of the engine. Fig. 2 a side elevation ofthetractioniengine. Fig. 3 a plan view partly in section showing thedriving connections between the motor and the traction wheels. Fig. 4asection on the line 44 in Fig. 3. Fig. 5 a section on the line 5- 5 inFig. 4.

The frame has the sides 1 and 2. Brackets 3 extend upwardly from thering 2 and are secured to an annular mounting 4 for the steering frame5. The steering frame 5- is rotatably mounted in the mounting 4.Brackets 6= extend downwardly from the frame 5. The axlesr'7 of thesteering wheel 8 extend into. bearing 9 carried by.

the brackets 6.

The traction wheels 10 are journaled on the axle' 11. The axle 11extends through the brackets 12 secured to the sides 1 of the frame. Thebrackets 12 are provided with the slots 13 in which the axle 11 isarranged. Blocks-14 are slidingly mounted in the slots 13 and rest onthe axle. arranged between the blocks 14 and the caps 16. The caps 16are secured t the brackets 12 by the bolts 17. These s rings form aspring mounting for the'fram'e of the trac tion engine on the axle. Atthe same time,

the movement of the axle relatively to the frame is controlled so as tomaintain the traction wheel in proper relation to its driving gearshereinafter described.

The motor 18 which as shown is in the form of an explosive engine is.mounted on a frameformed by the upper cross pieces 19,-

longitudinal cross pieces 20 and lower cross pieces 21. The lower crosspieces are bolted to the sides by means of the bolts 22.

The fly wheel 23 of the engine is utilized for one member of the clutch.The other member of the clutch 24 is fixed with relation to the shaft30. The clutch is actuated by the-lever 25 which is pivoted at 26 to theSpecification of I ette-rsBa tent.

differential case 27. The rod 28. runs from and 32 in the. transmissioncase 33. The

. transmission gears 34 are arranged on the shaft 30 and are adapted tobe thrown into mesh with the gears 35 on the driven transmission shaft36. These transmission gears operate in the ordinary manner and arethrown into and out of mesh by the lever 35. The lever 35 is pivoted ona shaft 58 extending across the frame and carried by bearings 58 onabracket 58" secured to the transmission case 33. The shaft 36 isjournaled in the bearings 37 and 38in the case 33. It will be noted thatthe transmission case is parted at 39 and 40, the parting passingthrough the centers of the bearings 31, 32, 37' and 38. In this manner,the parts of the case form the separable parts of these bearings so thatthe bolts 41 which extend entirely through the transmission case notonly secure all the parts of the transmission case but also the parts ofthebearings .formed with the case. 7

The lower member of the transmission case has the arms 42 which extendacross The driven transmission shaft 36 extends through the bearing 45in the differential case 27. A beveled gear 46 on the end of the shaft36 meshes a beveled gear 47 secured to the frame of the differentialgear. The differential gear may be of any type. As shown, it is of thespur gear type having the floating gear 49 and fixed gear 50. The gearsv50 are fixed on the cross shafts 51. Gears-52 are fixed on the ends ofthe cross shafts 51 and mesh the gears 53 on the traction wheels. Theshafts 51 are journaled in the bearings 27 arranged on the differentialcase.

The differential case has the arms or extensions. 27" which form a partof the case and extend from side to side of the frame. Shafts 51 arearranged in-these arms. Bolts 27"" extend through these arms and throughthe flanges forming the channel iron of the p by the bolts 27 securesnot only the partsof sides. It will be "noted that the differential caseis parted at 27 which parting extends through the bearings 27 andbearing 45. In

this manner it is practical tolm ake these different bearings directlyin the case.

bolting the. arms 27* to the sides of the frame the differential casebut also the parts of the bearings.- Q

Brake Wheels 54 are fixed on the shafts 51.

These are operated by the brake bands 55. The brake bands 55 areconnected by the rods v56 with the rock arms 57 fixed on the shafts 58.Thefoot levers 59 are also fixed on the shafts 58 and in close proximityto each other, the shafts 58 being separated between said levers. Byplacing the foot on both levers at once, both brakes may be set, or byoperating either lever 59, the brakes may be set independently of eachother. This is v useful in assisting in the steering of thevehicl e indi'ilicult places and also where one or the other of the traction wheelsby reason of the ground on which the engine is working has little or notraction. I

A clutch member 60 is fixed on the end of the driving transmission shaft30 and extends outside of the differential case A shaft 61 is carried bythe member 60 and the bearing 82. The bearing 62 is mounted on thebracket 63. The bracket 63 is secured on the ends of the sides of theframe. A cross shaft 64 is journaled in the bearings 65 also carried bythe bracket 63. A beveled gear 66 is fixed on the shaft 64 and meshes abeveled [gear 67 on the shaft 61. A belt pulley 68 is fixed on the shaft64. A clutch member 60 is slidingly mounted on the shaft 81 and lockedagainst rotation thereon by a spline and groove mechanism- The clutch isthrown out of engagement in Fig. 3 and in engagement in Fig. 1. Bythrowing in this clutch, the belt pulley 68 is actuated so that theengine may be used for power purposes.

A radiator 69 extends upwardly from the mounting 4. This radiator isconnected by the pipe 70 with the water system of the motor.

A steering cable 71 extends around the steering frame 5. It is securedto the shaft 72. A steering gear 73 shown in detail in Figs. 1 and 2 isarranged to actuate the shaft 72. A steering wheel 74 extends to thegear 73 by means of which the engine may be steered.

It is preferable for convenience of mounting and balancing the engine toplace the motor in front of the traction wheels. present arrangementwith the transmission Simply 'sition'for throwing the gears.

The

lgear a tthe rear of the axle gives ample opportunity for a desirablelength of shaft- .between the motor and the transmission gear and placesthis mechanism in convenient po- It is also preferable to have the gearsoperating on the tractionW'vheels in front of the axle in that thethrust of the gears tends to lift the frame and thus decreases. thefriction on the axle bearing. This construction provides a convenientway of so placing the gears operating upon the tractionwheels in thatthe differential may bephtced in front of the axle and readily connectedwith the tran smission at the rearfof the axle. This arrangement alsopermit's'of the placing of the operating mechanism all above themainframe so-that the different parts may be readily accessible.

What I claim as new is i 1. In a traction engine, the combination of aframe; traction wheels; an axle mopinted on the frame on which thewheels are meanted; a motor mounted on the frame; transmission gearingcarried by the frame at the opposite side of the axle from the motor; adriven shaft extending from themotor to the transmission gearing; adifi'erential gear at the opposite side of the axle from thetransmission gearing; a driven transmission shaft connecting thetransmission. gearing with the differential gear, said driving shaft anddriven transmission shaft being arranged on opposite sides of the axle;and adriving connection between the differential gear and the tractionwheels.

2. In, a traction engine, the combination of a frame; traction wheels;an axle on which the wheels are mounted; a spring connection between theaxle and the frame;

a motor mounted on the frame; transmission I BERT 0. BALL.
